Abstract: L'invention concerne une défibreuse (1) permettant de distribuer des fibres cellulosiques défibrées directement sur une toile de formage (5). Ladite défibreuse (1) comprend des nervures (33) s'étendant à l'intérieur d'un logement cylindrique (24). Lesdites nervures présentent des surfaces externes courbées qui dirigent les fibres dans une zone (35) dans laquelle des lames de piles (25) sont en action. Une grille (37) située en face d'une sortie (30) du logement circulaire (24) est prévue à la périphérie (35) de manière à permettre la rotation des lames de piles (25). Un espace ne laissant passer que les fibres est prévu entre les barres de la grille. Ainsi, les agglomérats sont renvoyés dans la zone de travail des lames de piles (25). Lesdites lames (25) agissent plusieurs fois sur les agglomérats, ce qui permet d'assurer que seules les fibres individuelles passent à travers la grille (37) et sont déchargées directement sur la toile de formage (5) depuis une ouverture de décharge (2) de la défibreuse (1). La largeur de l'ouverture de décharge (2) correspond, de préférence, à celle du produit à former sur la toile de formage (5).

Title: Device and method for dna amplification and assay
Inventor: COTTINGHAM HUGH V
IPC: C12Q1/68
Filed: 1996-09-10
Granted: 2001-12-11
Abstract: A DNA amplification and homogeneous DNA probe assay device is provided which includes a multiplicity of discrete sample cells in a flat "card" format, with each sample cell containing the reagents necessary for both DNA amplification and homogeneous DNA probe assay. The device is particularly suitable for fluorescence polarization DNA probe assays, and is preferably provided with an integral polarizer to avoid the need for polarizing elements in the related measuring apparatus. The size and geometry of the sampe cells allows for a "hot start" of the DNA amplification reaction and thereby avoids mispriming of the amplification reaction.

Granted: 2001-01-30
Abstract: Wide-band speech signals and also music signals are coded with relatively less computational efforts and less sound quality deterioration even at low bit rates. A spectral parameter calculator 200 obtains a spectral parameter from sub-frames of input signal from a sub-frame divider 120, and quantizes the obtained spectral parameter. A divider 410 divides the difference result from a subtractor 235 into a plurality of sub-bands. Adaptive codebook circuits 300 obtain a pitch prediction signal by obtaining pitch data in at least one of sub-bands. Judging circuits 420 execute pitch prediction judgment by using the pitch data in at least one of the sub-bands. A synthesizer 430 synthesizes a pitch prediction signal. A subtractor 230 subtracts the pitch prediction signal from the difference result from a subtractor 235 and thus obtains an excitation signal. An excitation quantizer 350 quantizes the excitation signal with reference to an excitation codebook 355.

Abstract: Dispersible additive systems for polymeric material include dispersant-coated pigments in a liquid nonaqueous polymeric carrier. The additive systems are most preferably in the form of a particulate nonaqueous paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being shaped (for example, prior to being spun into synthetic filaments). By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of polymneric material, shaped objects of the polymeric material (e. g., melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.

Title: A perceptual compression and robust bit-rate control system
Inventor: PAULS RICHARD JOSEPH
IPC: H04N7/26
Filed: 1998-10-14
Granted: 2002-03-05
Abstract: A method of compressing a source (e.g., a video signal, a still image, an audio signal, etc.) is disclosed that does not require the transmission of changes in the quantization step size and more evenly affects the fidelity of the source than techniques in the prior art that change the quantization step size at various points in the compression process. An illustrative embodiment of the present invention involves transforming a source (e.g., a video frame, audio sample, etc.) into m coefficients, in well-known fashion, wherein each of the m coefficients is represented by a known number of bits. Then, only n of the m coefficients are used for transmission or storage, as appropriate, where the n coefficients are more perceptually significant than the m-n coefficients not used.

Title: System for electronic repository of data enforcing access control on data retrieval
Inventor: MIRLAS LEV
IPC: G06F21/62
Filed: 1998-12-23
Granted: 2002-04-02
Abstract: When an electronic document is made available for review by other entities, it is often convenient to store the document in a repository or database managed by a third party. A system is provided in which the originator of the document is able to ensure the integrity and security of its document filed with a third party repository without having to trust the administrator of the repository. Both the document originator and the repository administrator have vault environments which are secure extensions of their respective work spaces. The vault of the document originator encrypts a document that it receives from the originator, prior to forwarding it on to the vault of the repository. On receipt of the encrypted document, the repository's vault signs the encrypted document itself before storing the document in the electronic repository and returns to the originator's vault proof of deposit of the encrypted document in the form of a copy of the signed encrypted document. An access control list identifying access ownership privileges for the document are also stored in the repository. Updates to the access control list are under the control of document originator, or another computer designated by the document originator. When a request is made to view the document, it is made from the vault of the requesting party (a secure extension of the requesting party's work space) to the repository's vault. The repository's vault retrieves a copy of the encrypted document which it forwards, along with the requestor's identity to the originator's vault. The originator's vault verifies that the access control is valid, then verifies that the requestor is authorized to view the document from the access control list, then decrypts the document and forwards the decrypted document directly to the requestor's vault. The requestor provides proof of receipt of the decrypted document.
